Solar + photography. It's a compound word. Plus it’s easier to say than "latent-exposure solar photograph." As simple as a soda can or an old 35mm film canister with a small hole in it can be a pinhole camera. Load it with black and white photo paper (not the kind to print on, but the kind that has light-sensitive resin on it [RC] or infused in it [Fiber] that is used for exposing film), seal out any light except for the pinhole, secure it to something that won't move, and leave it alone for however long. When a period of time has passed, and after some “processing” has been done, the results are, well, see for yourself......

(yes, this video is one of mine.)

not bad for a six-monther

rivers are really nice as long-term subjects. don't know what it is......just really like them.

vine-ripened solargraphy

usually it's curious people or the bomb squad that messes around with non-descript black canisters on fences and poles. or water damage. I guess 7 months is long enough for nature to just do it's thing.......

............and it did......

no flood insurance......

i cringed when i opened this one, but then again, after a few days of rain and weeks of condensation seeping in every morning, what do you expect? adds character, i think......

i do, on rare occasions, still get clear-ish results........like the one below.

6 month exposure

finally retrieved it after half a year. and there was a significant amount of water in the canister......yet it still turned out.

time-lapse

the guy next door is building a house, so naturally I wanted to document the whole process....but how? hmmm.....well, here it is, 4 months, 8 days later. the reason it looks like a sepia x-ray is due to the fact that the paper inside the camera takes on whatever it sees on the outside. technically, it took a picture every day for 128 days. you can tell when you look at the roof and can still see the tree line behind it. what's nice is that you can make out the sun trails for that long.

90 days

this one shows how much the sun moves from winter solstice (December 21) to spring equinox (March 20).

solar map

these two were attached to the back of a car(yes, a moving one) for a day of driving to and from "the coast." the sun's tracks aren't as bright as when the camera isn't moving, but it still shows how most of us travel in circles nonetheless.

on a bicycle

attach camera to basket on a bike, ride around normally, and you see a pattern that shows you tend to keep the same parking space...............
